Spinal Traumas and their Treatments According to Avicenna's Canon of Medicine.
Spinal Traumas have been categorized as disabling diseases that cause irretrievable personal and social problems. Having conducted a rather comprehensive diagnosis of the anatomy of the backbone and spinal cord as well as their functions, Avicenna (Ibn Sina, 980-1037) stated the levels and kinds of spinal impairments that are caused by spinal traumas in his great masterpiece Al-Qanun fi al-Tibb (The Canon of Medicine). ⋯ Avicenna had used the following methods to treat spinal traumas: food and drug therapy and regimental therapies such as massage, phlebotomy, cupping, dry sauna, and surgery. The authors of the present article review the bases of Avicenna's viewpoints regarding spinal traumas and their treatment.

Review Case Reports
Osteomalacia-Inducing Tumors of the Brain: A Case Report, Review and a Hypothesis.
Osteomalacia-inducing tumors (OIT) are mesenchymal tumors that characteristically secrete fibroblast growth factor 23, resulting in a paraneoplastic syndrome of hypophosphatemic osteomalacia. These tumors are known to occur in soft tissues and bones in various sites. It is very unusual for OITs to occur intracranially, with only 10 reported intracranial cases since their discovery in 1959. The most common intracrainal OITs are phosphaturic mesenchymal tumors and hemangiopericytomas. We report a case of hypophosphatemic osteomalacia caused by a tumor in the right anterior cranial fossa. We also hypothesize, based on our review of the literature, that this entity is underdiagnosed. ⋯ The diagnosis of OIT should be considered in a case of severe hypophosphatemia and metabolic bone disease that is not explained by any other metabolic or hereditary disease. These tumors can occur intracranially and may be confused with a meningioma or a hemangiopericytoma. Taking OIT into consideration in such cases could lead to a shorter time to diagnosis and management, which in our case took 4 years.

Review Case Reports
Intramedullary Solitary Fibrous Tumor--A Benign Form of Hemangiopericytoma? Case Report and Review of the Literature.
Solitary fibrous tumors (SFTs) are benign tumors of the soft tissue occurring anywhere in the human body but arise predominantly in the visceral pleura. SFTs of the central nervous system are rare, especially when they occur within the spinal cord. ⋯ There is evidence that SFTs and hemangiopericytomas (HPCs) are not different entities but should be considered as different graduations of a common spectrum. The extent of resection is a prognostic factor for recurrence-free survival in SFT; therefore we recommend surgery with complete resection whenever possible depending on the results of mandatory intraoperative neurophysiological monitoring in these cases.

The Impact of Neurosurgical Complications on Patients' Health Status: A Comparison Between Different Grades of Complications.
The aim of this article is to investigate the frequency of neurosurgical complications according to Landriel-Ibañez Classification and their impact on patients' health status. ⋯ Our study highlights the impact of neurosurgical complications on patients' life and contributes to the debate on how define and classify adverse events because a classification only based on treatment seems to be not adequate.

Scalp metastases of meningiomas seldom have been reported. Here, we report a series of 4 cases of this rare event and discuss the relevant potential risk factors. ⋯ Spreading of meningioma cells during surgery is a possible mechanism for scalp metastases of recurrent meningiomas. Factors associated with scalp metastases include reoperations, immunosuppression, radiation therapy, torpid course of the surgical wound with cerebrospinal fluid fistula, and histologic progression. Awareness of these features is advisable for neurosurgeons involved in the care of patients with similar profiles.
